My friend, Vincent recommended me the film. I'd guarantee that you'll love the film and it won't waste your time.
I totally got blew away by the relationship of these two contrasted characters - the aristocrat, Philippe and the new caretaker, Driss who lives in the ghetto. Their friendship is both heartwarming and touching from the way they spend time together. It was so beautifully and well-filmed.
On my part, I think I have something to argue about. Well, I just refer what I've learned in class. The movie was actually based on a true story and if we notice at the end of the film, they introduce the real-life persons involved and Driss was not even black. If we go back to the content of the movie, the duo do spend time a lot of going here and there, making fun of each other, especially Driss who has the comical characters. If we try to imagine using a white guy to replace black Driss, maybe the effect won't be as good as using black, that would be tasteless. That, go back to stereotypes.
If you want to read about the reviews and the bits of the story, this one reflects the French society based on the film and this is more professional reviews, both written waay better than me. Oh, the movie is in French by the way.
